In particular, products that are used on a daily basis, such as underwear, socks, bedding, rugs, and tatami mats, become a source of nutrients when secretions excreted from the human body or bed, peeled skin, food scraps, and other substances adhere to them. It becomes a suitable medium for the reproduction of mites. Therefore, these products are treated with chemicals to give them anti-mite effects.

Conventional insecticides for indoor dust mites include the epidemic prevention insecticides fenitrothion, fenthion, diazinon,
Provoxul, resmethrin, phenotrin, etc., and diethyltoluamide, a blood-sucking insect repellent, were used, but later, the efficacy of benzyl benzoate, phthalimide compounds, isobornylthiocyanacetate, dehydroacetic acid, etc. It has been effective.

[Problem to be solved by the invention] However, the above-mentioned epidemic prevention insecticides are originally used to exterminate flies and cockroaches, and they have a unique unpleasant odor and irritation. Furthermore, there are restrictions regarding safety, and it cannot be used freely on the body or in the living environment.

Furthermore, although the latter various chemicals exemplified above have been proposed to eliminate the drawbacks of the above-mentioned insecticides for epidemic prevention, these are still not necessarily satisfactory in terms of odor, efficacy, etc.
